f Y l l* IMPnOVEMENT 1N cuTTER-STOCK FOR, SWIVEL-P Lcws.,

` The Schedule referred/to in these Letters Patent' and makngpat of thesame.

' That I, ELBRIDGE @.jllIATTHEWs', of Oakham, in'

the county of Worcester'and Gommonwealthot' Masf` sachnsetts,haveinvented certain new and useful Improvementsin Gutter-stock forSwivel-flows; and I` do `.hereby declare that the following is a full,clear, and exact description'of .the same," reference being had to 'theaccompanying drawings forming a part'oi this 'Figure llrepresents a side'iew of my-hnl'n'oved swi \el cntter,stock, and the `plo`w-beam to whichit is attached, and' Figure '2 represents a'transverse vertical sectiononline A B, fig. 1. A

- 'Tocn'able those skilled in `the art to which my invention belongstornake'and-use the same, I `will pro- .ceed to describe itmorein'detail'.

The'nature of my invention consists-l First?, in a hinged or swingingcutter-stock, as here- Second, in the combination with a hinged orswing'- A. ingcutten'stck, ofadevice Vfor-adjusting the cutterstock fromright 'to left, and cica cerca, as hereafter explained.

In -the drawingsil 'represent-s the plow-beamte bolts a a, which passthrough the ends of said plate, as fully indicated in fig. 1` ofthedrawings.

In. the 'lower sidel of the holding-plate, is formed a d0vetail'groo\e,for the reception 'of an adjusting and` Thelower side of the wedge :l ismadev with a double bevel, which inclines towards its central part,thereby forming two inclined planes or wedges 1 '1, one at leachenthto'fit bevels .2 2, formed on 'theupper sideof the cutter-stock,'asfully indicated in the drawings fig. 2. -I'do not confine myself to `anyparticular' mode of adjusting the hinged cutter-stock B, as variousdevices may be employed'for that purpose.

It is very desirable to have a movable cutter on a swiuel-.plomso that.itfcan be adjusted to cut in line with the land-side, or standard, whenturning or plowing either rglit or left-hand fui-rows, andwhchnecessitates the movement of' the. cutter, from side to side, from oneto three inches, -according to the differencel iu construction of theplows.

From the foregoing description it will he seen that this adjustment canbe'-obtaned'-very readily by4 my invention, since the cutter-stock B andcutter D, can be Yswung from-right to left and cioe tersa, by thesimple' movement ofthe wedge from side to' side, and it is at the same4time held firmly in such adjusted position bythe action of said wedge.v

4Having., described my'fimproved cutter-,stock for swivel-plows, 1

What 1 claim therein as new and of my invention,

and desire to secure b'y Letters. Patent, is-i- 1. The cutter-stock Bfor supporting the'sward-cutter of a plow, when hinged tothe plow-beam,suhstantia-lly as and for the purposes stated.`

2.' 'lhe combination with a hinged, or swinging cutter-stock, ofthewedge d'ofequimleut device for, atl-- justing thesanie from righttoleft, 'or vice versa.
